The Real Madrid star’s appearance in the top two’s La Liga clash was thrown into doubt after it was claimed he insulted a referee.
Ronaldo shouted in the official’s face during last week’s Madrid derby against Atletico after a decision went against him.
Barca legend Lionel Messi was recently banned for four internationals after insulting a referee while playing for Argentina, with the Catalan press demanding the same action is taken with Messi.
Ronaldo is already on four yellow cards and must avoid a booking against Sporting Gijon on Saturday to ensure he is not automatically banned for the Bernabeu game on April
Table-toppers Real are three points ahead of their bitter rivals, with a game in hand.
